BOOKBINDER.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed February 16, 1912. Serial No. 678,039.

To all whom it may concern Be it known that I, ROBERT J. NICHOLSON, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Bookbinders, of which the following is a full, clear,concise, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification.

My invention relates to improvements in book-binders or holders, and hasfor its ob ject the provision of novel and effective mechanism wherebyfillers or books may be readily placed within or removed from theircovers or back elements. A construction devised for the purpose is alsodisclosed in my application Serial No. 367,938, filed April 13, 1907.

The nature and advantages of the construction of my present inventionwill be fully? understood from the following description of thepreferred embodiment of the invention, shown in the accompanyingdrawing. in which Figure 1 is a perspective view of a part of the bookstructure; Fig. 2 is a plan view of a part of the structure shown inFig. 1; Fig. 3 is a view of the structure shown in Fig. 2 with one ofthe parts in another adjustment; Fig. 4 is a sectional view on line 4 4of Fig. 2; and Fig. 5 is a sectional view on line 5 5 of Fig. 8.

Like parts are indicated by similar characters of reference throughoutthe different figures.

The back element 64 preferably constitutes a separable cover designed toengage the backs of books or fillers, such as pamphlets, magazines,etc.. a book Z) being shown pro vided with such a covering. In orderthat this back element a may engage the back of the book, it ispreferably provided with upwardly extending arms 0 that are secured tothe back element in any suitable way. In the preferred embodiment of theinvention, these upwardly extending arms constitute the angular ends ofa metal strip (Z, which is caused to form a part of the back element a.The arms 0 0 are provided with openings therein for the reception of abar 6, preferably of metal and desirably oblong in cross-section toenable it to be held from rotating, turning, or shifting, by the twoportions of the book or filler between which the bar is disposed, forapurpose which will appear. That end of the bar which engages the arm 0desirably passes through an open- 111g therein and is so related theretothat it may, while maintaining its engagement with the arm 0, be swungsul'liciently clear of the cover, to enable a book to be placed within,or removed from, the cover. In the preferred embodiment of theinvention, this end of the bar is desirably wedge-shaped so as to limitits outward projection, and is bent up at its extreme end to constitutea fastening device to prevent the withdrawal of this end of the bar. Ido not wish to be limited, however, to the manner in which the arm 0 isassociated with the bar 6 in carrying out the object of my invention.The arm 0 is designed to have separable engagement with the remaining orsecond end of the bar, the entire arrangement being such that the barmay be turned or rotated, partially or completely, the bar in one of itspositions being adapted to have its said second end disengaged from thearm 0 and in an alternative position being held by the arm The book,itself, serves to hold the bar in its latter position.

In carrying out the object of my inven tion, the arm 0 is provided withan opening 0 having a restricted outlet 0 lying in the plane that themajor portion of the bar occupies when being normally held by the book.The portion, or second end of the bar 6, that is adjacent to the arm 0is bent or twisted to occupy a plane that is transverse o-r angular withrespect to the plane occupied by the balance of the bar, whereby saidsecond end of the bar may not be withdrawn through the restricted outlet0 when the book is in normal relation with the cover or back elementwithin which it is disposed, the arm 0? then surrounding the twisted endof the bar.

When it is desired to remove the cover from the book, the book is openedat the place where the bar is located and then laid flat, whereafter thebar is given a quarter turn to bring its second or twisted end into thesame plane with the restricted outlet 0 to permit of the elevation ofthe bar, so that the book may be inserted within or withdrawn from theback element or cover.

I believe it to be broadly new with me to provide a construction whereinthe book is adapted to hold the bar so that the bar is held inengagement with the back element in order to hold the book in place, andwhile I prefer to employ a construction by which the book holds the barfrom material turning movement for the purpose stated, I do not wish tobe limited to such construction in all embodiments of my invention.

While I have herein shown and particularly described the preferredembodiment of my invention, I do not wish to be limited to the preciseconstruction shown, as changes may readily be made without departingfrom the spirit of my invention.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent the following:-

1. A device for holding books, including a. back element carrying an armprovided with an opening having a restricted outlet, a bar adapted-to beengaged at its ends with the back element and adapted for insertion between the leaves of the book to be held and having a fastening portionadapted for passage through said restricted outlet and adapted to bereceived by the opening in said arm, said bar being rotatable orturnable about an axis extending longitudinally of the back element,whereby the part thereof received by the opening in said arm may bebrought into position, to be passed through the outlet from said openingor may be brought into position to have its passage through said outletprevented, the bar having unequal cross-sectional dimensions, whichpermit it to be held by the book when in normal relation with the bar,to prevent the bar from being moved to that position in which thefastening portion may be moved through the outlet provided for theopening in the arm.

2. A device for holding books, including a back element carrying an armprovided with an opening having a restricted outlet, a bar adapted to beengaged at its ends with the back element and adapted for insertionbetween the leaves of the book to be held, the portion thereof receivedbetween the leaves of the boo-k having unequal cross-sectionaldimensions, in order that the book that is being held may hold the barin relation to the book, the end portion of the bar adjacent to said armalso having unequal crosssectional dimensions, the said two portions ofthe bar lying in different planes, whereby the book may hold the bar toprevent the end portion of the bar from being removed through saidoutlet, said bar being rotatable or turnable about an axis extendinglongitudinally of the back element when the book is opened, in order topermit said end portion to be moved through said outlet.

3. A device for holding boo-ks, including a back element carrying onepart of a fasten-- ing device and a bar adapted to be engaged at itsends with the back element and adapt ed for insertion between the leavesof the book to be held, and carrying a fastening part complemental tothe aforesaid part of the fastening device, said bar being rotatable orturnable about an axis extending longitudinally of the back element,said parts of the fastening devices being separable when the bar isrotated to occupy one position, and being inseparable when occupying analternative position, the bar having unequal cross-sectional dimensions,which permit it to be held by the book when in normal relation with thebar, to prevent the bar from being moved to that position in which theaforesaid complemental parts of the fastening device may be separated.
